The original work by author Richard Barnett drew heavily on the Library's holdings. Subtitled Blood, Guts, Brains and Babies, the tour begins at Lincoln's Inn Fields and covers approximately three miles. On average it should take around two hours to complete, but of course depends on your pace - and how sidetracked you get.

If you can't get to Bloomsbury to hit the pavements for yourself, we would still heartily encourage you to check the free app out (or indeed, viewing the content online). For those who are in and around London this coming October another series of medically-themed free walks are scheduled for the Bloomsbury area. Keep an eye on the Wellcome Collection website for more details.
